** 2011 December 16, Denis Campbell, “Hospital staff 'lack skills to cope with dementia patients'”, in Guardian‎:"This shocking report proves once again that we urgently need a radical shake-up of hospital care," said Jeremy Hughes, chief executive of the Alzheimer's Society. "Given that people with dementia occupy a quarter of hospital beds and that many leave in worse health than when they were admitted, it is unacceptable that training in dementia care is not the norm."
** 2019 December 18, Richard Clinnick, “Railway's 2020 vision”, in Rail, page 3:Projects such as the King's Cross refurbishment, Waterloo blockade, Scottish electrification and the Borders show that the industry can do wonderful work - but that must become the norm, not the exception.

* (philosophy, computer science) A sentence with non-descriptive meaning, such as a command, permission, or prohibition.
* (mathematics) A function which satisfies a particular set of formal conditions, created to generalize the notion of the length of a vector. Formally, a real-valued function on a vector space, generally denoted $v\mapsto \left|v\right|$ or $v\mapsto \left\|v\right\|$, that satisfies the following properties:
** if $v\neq 0$ then $\left\|v\right\|\neq 0$;
** given a scalar $k$, $\left\|kv\right\|=\left|k\right|\cdot \left\|v\right\|$, where $\left|k\right|$ is the absolute value of $k$;
** given two vectors $v,w$, $\left\|v+w\right\|\leq \left\|v\right\|+\left\|w\right\|$ (the triangle inequality).
* (mathematics) Any of several generalizations of the above: a field norm, ideal norm, etc.
** (algebra) An element of the image of some (generalized) norm, the element then said to be from the norm in question, or from the structure which gave rise to the norm.
    A quaternion algebra $(a,b)$ over $k$splits if and only if $b$ is a norm from the field extension $k({\sqrt {a}})/k,$ i.e. if and only if there is some $x$ in $k({\sqrt {a}})$ which has field norm exactly equal to $b$.
* (chess) A high level of performance in a chess tournament, several of which are required for a player to receive a title.
